Abstract
The utility model relates to a kind of curved surface net frame four crutch mounting structure, rotate on the top of main support cylinder and around the central axis of main support cylinder and be provided with four sub-support cylinders extended obliquely, described sub-support cylinder forms front construction section together with main support cylinder, construction section after each sub-support cylinder is equipped with, rear construction section has upper and lower the cast steel spherical structure, the fusiformis cylinder that arrange respectively, and the upper end of fusiformis cylinder and junction plate hinged fixing, the lower end of fusiformis cylinder around main support cylinder top rotary setting and be welded and fixed with it.The utility model structure is simple, reasonable in design, is different from traditional mounting structure, and achieve rack, point crutch, temporary support graded crossing carry out, can form the main support structure of rack, it is efficiently convenient to install, while structural strength high, with low cost.
Description
Technical field
The utility model relates to a kind of curved surface net frame four crutch mounting structure.
Background technology
In known technical field, in the current long span building structure such as terminal, stadiums, conference and exhibition center, station at home and abroad, roof structure adopts the very many of complex-curved rack, its underpart supporting construction adopts frame column (steel column or reinforced concrete post and profile steel concrete column) usually, point crutch occurred in recent years, owing to having the advantages such as attractive in appearance, structure stress is reasonable, is more and more subject to the favor of architect and structure teacher.For the complex-curved space truss structure by large-scale bifurcated elastic supports, common construction and installation are generally first install a point crutch, take full hall scaffold afterwards and install rack.The shortcomings such as this mounting method has long construction period, and full hall scaffold expense is high.In addition, when the node of bifurcated column top adopts centripetal joint point, adopt conventional installation methods not easily to ensure the accurate location of centripetal joint point, may have a negative impact to the stressed of structure.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, and provide a kind of curved surface net frame four crutch mounting structure, can form the main support structure of rack, it is efficiently convenient to install, and structural strength is high, with low cost simultaneously.
The utility model solves the technical scheme that its technical problem adopts: a kind of curved surface net frame four crutch mounting structure, comprise the some main support cylinders erect upward, rotate on the top of described main support cylinder and around the central axis of main support cylinder and be provided with four sub-support cylinders extended obliquely, described sub-support cylinder forms front construction section together with main support cylinder, construction section after each sub-support cylinder is equipped with, on described rear construction section has, the lower cast steel spherical structure arranged respectively, fusiformis cylinder, the junction plate that described cast steel spherical structure has spherosome and is connected as a single entity with spherosome, the external surface of each cast steel spherical structure is equipped with rack web member, described fusiformis cylinder is that two ends are thin, shape broad in the middle, and the upper end of described fusiformis cylinder and junction plate hinged fixing, the lower end of described fusiformis cylinder around main support cylinder top rotary setting and be welded and fixed with it.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, is different from traditional mounting structure, achieve rack, point crutch, temporary support graded crossing carry out, mainly contain following features:
(1) erection sequence is not merely according to conventional method from bottom to up, and adopts solid space to install;
(2) installation of rack can be carried out with the installation of point crutch hypomere simultaneously, adopts interim lattice column, do not adopt full hall scaffold when rack is installed;
(3) solder sphere be connected with centripetal joint point and to connect otic placode high-altitude when rack is installed in place;
(4) crutch epimere hoisted in position after rack installation is divided;
(5) above-mentioned erection sequence sectional is intersected and is carried out, can obvious accelerating construction progress.When such as certain section is installed and divided crutch epimere, the rack that simultaneously can carry out next section is installed;
(6) installation and removal of interim lattice column is determined with the order of installing section, completed section (rack of this section and a point crutch complete all) dismountable interim lattice column for next Work sectors, significantly decrease the quantity of required interim lattice column, reduce installation cost.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The preferred embodiment of a kind of curved surface net frame four of the utility model as shown in Figure 1 to 4 crutch mounting structure, comprise the some main support cylinders 1 erect upward, rotate on the top of main support cylinder 1 and around the central axis of main support cylinder 1 and be provided with four sub-support cylinders 2 extended obliquely, described sub-support cylinder 2 forms front construction section together with main support cylinder 1, construction section after each sub-support cylinder 2 is equipped with, on described rear construction section has, the lower cast steel spherical structure 21 arranged respectively, fusiformis cylinder 22, the junction plate 212 that described cast steel spherical structure 21 has spherosome 211 and is connected as a single entity with spherosome 211, the external surface of each cast steel spherical structure 21 is equipped with rack web member 23, described fusiformis cylinder 22 is thin in two ends, shape broad in the middle, and the upper end of fusiformis cylinder 22 and junction plate 212 hinged fixing, the lower end of described fusiformis cylinder 22 around main support cylinder 1 top rotary setting and be welded and fixed with it.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
